BRAKE MECHANISM.

To all whom it may concern:

Be it known that I, JUs'rUs J. Ross, a

citizen of the United States of America, and

resident of Fairmont, county of Marion, and State of lVest Virginia,have invented certain new and useful Improvements in Brake Mechanism, ofwhich the following is a specification.

This invention relates to improvements in car-controlling brakes, and'more particularly to a brake adapted for use on minetipples whereby themovement of thecars being loaded at the tipple may be controlled; and itconsists in theparticular construction, arrangement and combination ofparts which will hereinafter be fully described.

The primary object of the invention is to provide a simple, positive andconvenientlyoperated drum brake for use on loading tipples and the likewhereby the movement of railway cars from one position to another withrespect to the loading chute of the tipple may be readily controlledfrom the top of the tipple and, consequently, without resorting to theuse of the brakes on the .cars, resulting in the need of a man foroperating such car brakes being dispensed with.

As is well known, the railway tracks at a loading tipple are usuallyarranged on a slight incline for facilitatii'ig the forward movement ofthe cars as needed for loading and after loading. By means of thepresent invention, cars are readily releasedv and allowed to move slowlyforward down the incline,'and are readily stopped at any desired point,

A further object of the invention is to provide a strong and durablebrake of the character mentioned, the construction being such as toreadily withstand the great strains and heavy shocks to which it isliable to be subjected.

'In describing the invention in detail, reference is herein had to theaccompanying drawin s formin :1 )art of this s cifica-- t-ion, in whichFigure 1 is a front elevation of the inventionmounted in operativeposition; Fig. 2 is a side elevation of the-same; Fig. 3 is a top planView of the same; and Figs. 4 and 5 are sections taken respectively onthe lines 4-4 and 55, .Fig. 3.

Referring to said drawings, in which like reference characters designatelike parts throughout the several views-1 mdlcates Specifieation ofLetters Patent.

Application filed March a, 1909. serial No. 481,127.

the base-plate of a frame which is adapted to be mounted upon a beam 2,or in other appropriate position at the top of a loading tipple, saidframe comprising said base-plate l and a pair of outwardly-directedparallel supporting arms 3 and 4- which are preferably integral with theplate 1 and which are terminated by shaft-bearing portions 5 and 6,inwhich latter is journaled a shaft 7. A drum 8 is keyed upon the shaft7 between the arms 3 and 4 by means of a key 9 fitting in registeringmortises provided in said shaft and in the drum, as is clearly shown inFigs. 4 and 5, and upon this drum is wound a cable 10 one end of Whichis appropriately attached to 'said drum, as shown in Fig. 4. Saidcable'is passed downward from the drum to and about a sheave 11, andthence forward for connecting to a car. -A brake-wheel 12 is fixeduponthe shaft 7 adjacent to the bearing portion 5, a key v 13 beingfitted into registering mortises provided insaid shaft and said wheel,as shown in Figs. 2 and 5. Partially encircling the Wheel 12 is aflexible metal brake-band 14, on the inner surface of which is carried asectional brake-shoe 15 of wood or other suitable material adapted forfrictionally engaging said wheel. One end of the brakeband 14 isconnected by means of a strap 16 to the outer end of aforwardly-directed supportl? which is carried by, or which is formedintegral with, the frame, and the opposite end of said band is connectedby free'end of the lever 19 is a weight 21, preferably-adjustable,whereby force is applied to the brake-band for normally maintaining thebrake applied to the wheel, 12, resulting in the drum 8 being maintainedin a stationary position.

.The support 17 is formed integral with and receives support from thearm 3, as is clearly shown in Fig. 2. Said support is of hollow box-likeformation, providing two parallel vertical members 17, an upper crossmember 17*. and a downwardly and inwardly inclined member 17. The innermember 17) is in vertical alinement with the hangs the brake-wheel inappropriate position for having the lever 19 mounted thereagainst inproper relation to the brakeband ll. The two members 17 serve assupports or separated bearings in which are held the strap-attachingbolt 22 and the pivot-bolt 23.

in practice, the weight 21 occupies position on the lever which willnormally maintain the drum stationary. When the free end of the cablehas been attached to a car and it is desired to allow the car to moveforward down the inclined track, the weight is either moved forwardalong the lever or the free end of the latter is raised relieving thenormal pressure of the brakeshoe upon the brakewheel. This action al.-lows the shaft 7 and the drum 8 to turn, paying out the cable 10. it isobvious that by manipulation of the lever the speed of the car in movingforwardmay be readily controlled and the car may be stopped at anydesired point.

The device may be operated by the same person who controls the dumpingof the .znine cars at the top of the tipple.

Having thus described my invention, what it claim new, and desire tosecure by Letters Patent, is-

Leashes In a drum-brake for use on loading'tipplesya base-plate adaptedfor mounting in vertical, position; a pair of parallel outstanding armscarried by said base-plate; a shaft journaled in said arms; a drum fixedon said shaft; a brake-wheel fixed on said shaft; a hollow box-likesupport connected to one of said arms, said support comprising a pair ofparallel vertical members, an upper cross-member, and a downwardly andinwardly inclined member, the inner of the vertical members being invertical aline-.

ment with said one arm and the outer of said members being inoverhanging relation to said brake-wheel; a brake-band encircling saidbra-kewheel; a strap connecting one end of said bralre band to the outerend or" said support; a lever pivoted intermediate its ends against thebrake-wheel overhanging member and having an end pivotally connected tothe opposite end of said strap, and means for adjusting said brake-band.

in testimony whereof ll aflix my signa v fmeion Gnarrins.
